        From my knowledge, it’s kinda the opposite - when a device first runs out of battery, it’s almost always the case that only one of the batteries is truly dead. So if you find that one dead battery and swap it out, you’ll be good again for a surprisingly long while

          Depends on whether the batteries were hooked up in either series or parallel. Later GameBoys only needed 2 batteries but required the same voltage, so I’m guessing that the OG GB is wired in series-parallel.

          So in other words, you need at least two batteries to be good for this to work in the OG GB. Later editions need both batteries to hold a charge to reach 3V.
